The Next Frontier of Blockchain Scaling: A Deep Dive into ZK Rollups

1. The application of zero-knowledge proofs (ZKPs) in the blockchain field has been widely discussed, but there are misunderstandings about their actual effectiveness in achieving privacy and scalability.
2. ZK rollups mainly utilize the simplicity property of ZKPs rather than the zero-knowledge property, which means that transaction data and account information are not fully protected.
3. For some types of decentralized applications (DApps), such as Web3 games and DeFi lending protocols, using ZK rollups may not be the best choice because the process of generating ZKPs may become a performance bottleneck or affect services.
4. In the current ZK Rollups implementation, the zero-knowledge principle is not fully followed, especially in components such as sequencers, providers, and rollup nodes, where users' transaction details and account information may not be fully protected.
5. Although ZK technology has potential in theory, it still faces technical and practical challenges in practical applications, and further technological progress and optimization are needed to fully realize its advantages.
